  • Work with data science teams to understand their data needs and help develop solutions to meet those needs.
  • Learn to build and maintain ETL and ELT workflows that extract, transform, and load data, ensuring it is processed accurately.

  • You have strong SQL skills with experience optimizing performance of relational database queries
  • You have at least basic understanding of the trade-offs between different data storage formats and technologies. Experience with frameworks like Dagster or Spark for building scalable data pipelines is a plus.
  • You’re dedicated to developing your skills in data engineering and excited about growth opportunities.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
